The Terrain Is Everything; The Germ Is

Men Who Believe Too Firmly In Their Theories, Do Not Believe Enough In The Theories Of Others. So ... These Despisers Of Their Fellows ... Make Experiments Only To Destroy A Theory, Instead Of To Seek The Truth.

A Discovery Is Generally An Unforeseen Relation Not Included In Theory.

A Man Of Science Rises Ever, In Seeking Truth; And If He Never Finds It In Its Wholeness, He Discovers Nevertheless Very Significant Fragments; And These Fragments Of Universal Truth Are Precisely What Constitutes Science.

The Terrain Is Everything; The Germ Is Nothing.

To Be Worthy Of The Name, An Experimenter Must Be At Once Theorist And Practitioner. While He Must Completely Master The Art Of Establishing Experimental Facts, Which Are The Materials Of Science, He Must Also Clearly Understand The Scientific Principles Which Guide His Reasoning Through The Varied Experimental Study Of Natural Phenomena. We Cannot Separate These Two Things: Head And Hand. An Able Hand, Without A Head To Direct It, Is A Blind Tool; The Head Is Powerless Without Its Executive Hand.
